FAN ATTACHMENT FOR ROCKING-CHAIRS.

Specification of Letters Patent.

Patented Feb. 22, 1am.

Application fi1ed. December 21, 1914. Serial No. 878,360.

To all whom it may concern:

Be it known that I, ANTHONY J. SoHRon- DER, a citizen of the United States, residing-at Donaldsonville, in the parish of Ascension andState of Louisiana, have invented certain new and useful Improvements in Fan Attachments for ROckingChairs; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to fan attachments for rocking chairs, and consists in an improved device of the typeshown in my similarly entitled co-pending application Serial No. 813,918, filed January 23, 1914.

It. is an objectof the present invention to provide a fan attachment for rocking chairs that will be of simplified construction over my formerdevice and of improved operation, and the invention consistsin constructions, combinations and arrangements hereinafter described and claimed.

In the accompanying drawings forming a part of this application, and in which similar reference symbols indicate corresponding parts in the several views: Figure 1 is a" side elevational view of a rocking chair illustrating one embodiment of my invention applied thereto and shown partly in section. Fig. 2 is a fragmentary elevational view,

partly in section, of the driving connections therefor. Fig. 3 is afront elevational view of the same with the gear casing removed. Fig. 4 is a fragmentary side elevational view of a rocking chair provided with 'a slightly modified form of the invention. Fig. 5 is a front elevational view, partly in section, of the driving connectionsofthe device as shown in Fig. 4; Fig. 6 is a side elevational view, partly in section, of the same illustrating the gear casing; Fig. 7 is a sectional View taken on the line 7-7 of Fig. 1; and Fig. 8 is a fragmentary slde. elevational vlewof a modified arrangement,

of the fan.

Referring to the drawings, and particularly to Figs. 1 to 3 inclusive thereof, the

rockers 1, upon which the chair 2 is supported, are connected by front and rear cross bars 8 and 4, respectively, preferably of tubulalr construction, as shown, Upon the rear tubular cross bar 4 is mounted a stub post 5, constructed with a yoke 6 for supporting the driving connections, as will hereinafter appear. The stub post 5 may be, as

illustrated, formed at its lower end with a collar 7, whereby the same is slidably mounted upon the tubular cross bar 4 and secured against displacement thereon by set screw 8. In the upper end of the stub,

post 5, above the yoke 6, is supported a tubular standard 9, held to position by a clam or other device 10 en a in the chair back; and the tubular standard 9 is preferably of brass, although the same may be constructed of any other suitable material.

In the standard 9 is included a telescopic section, as indicated at 11, for permitting the standard to be conveniently taken apart and packed for transportation. The standardis further bent at its upper end above the chair back into a substantially horizontal arm 12, and terminates in a downwardlydirected free end 18, arranged to support the fan 14. In the tubular standard 9, and in the horizontal arm 12thereof, are included slip orother joints 15 and 16, respectively, for permitting the fan to be horizontally swung to either side of the occupant of the chair, and adjusted in a vertical plane to direct the air currents from the fan to in the tubular standard andconnected at its lower end, as advantageously disclosed in Fig. 2, in a socket formed in a bearing sleeve 18. The bearing sleeve 18 is journaled to rotate in a plug 19 mounted at the base of the tubular standard 9, and is provided at its lower projecting end with a beveled pinion 20. The pinion 20' meshes with a beveled gear wheel 21, mounted on a shaft 22 journaled in the yoke 6, and fixed against rotation. On the shaft 22, to either side of thebeveled gear wheel 21, are mounted a pair of flanged pulleys-23 and 24 constructed with ratchets 25 and 26, for engaging spring-pressed pawls 27 and 28 mounted on the beveled gear wheel 21.

As advantageously shown in Fig. 2, each of the pulleys 23 and 24 is formed with a and 32, connected at their outer endsto the sition, as hereinafter described. Tothepul-= armsmay' beprovidedwvith series of perfol-latter to secure any desired throw of said=lethrough a-slot 37 in a, ed on the yoke 6.
